Money, Fiscal Policy, and Interest Rates: A Critique of Modern Monetary Theory

This paper examines modern monetary theory (MMT). MMT is a restatement of established Keynesian monetary macroeconomics and so there is nothing new warranting a separate nomenclature. MMT over-simplifies the challenges of attaining non-inflationary full employment by ignoring dilemmas posed by the Phillips curve, maintaining real and financial sector stability, and an open economy. Its policy recommendations take little account of political economy difficulties, while its interest rate policy recommendation would likely generate instability. On the plus side, MMT's advocacy of expansionary fiscal policy is useful at a time when too many policymakers are being drawn toward mistaken fiscal austerity.
